Function
General-purpose I/O port: Valid when the data output specification is
prohibited on UART0.
UART0 data output: Valid when the clock output specification is permitted
on UART0 .
General-purpose I/O port: Valid when the clock output specification is
prohibited on UART0.
UART0 clock input/output: Valid when the clock output specification is
permitted on UART0.
General-purpose I/O port: Valid when the data input specification is
prohibited on LIN-UART1.
UART1 data input. Because this input is used as necessary while UART1
is used for input operation, the port output needs to be disabled except
when it is used intentionally.
External interrupt input. Because those inputs are used as necessary
while the pertinent external interrupt is enabled, the port outputs need to
be disabled except when they are used intentionally.
General-purpose I/O port: Valid when the data output specification on
UART1 is prohibited.
LIN-UART1 data output: Valid when the data output specification is
permitted on LIN-UART1.
General-purpose I/O port: Valid when the clock output specification is
prohibited on LIN-UART1.
LIN-UART1 clock input/output: Valid when the clock output specification
is permitted on LIN-UART1.
General-purpose I/O port
Address strobe output: Valid when the address strobe output is permitted.
General-purpose I/O port
System clock output: Valid when the system clock output specification is
permitted. A clock with the same frequency as that external bus operation
frequency is output at this pin (Clock output stops at transition to the
STOP state).
General-purpose I/O port : Valid when the data input specification is
prohibited on LIN-UART2.
LIN-UART2 data input. Because this input is used as necessary while
LIN-UART2 is used for input operation, the port output needs to be
disabled except when it is used intentionally.
External clock input for free-run timer 0
Chip select 0 output: Valid when the chip select 0 is permitted to output.
